Composition and method for electroding dielectric ceramics

Claim 1

THE METHOD OF PRODUCING A MULTI-LAYER DIELECTRIC CERAMIC COMPRISING THE STEPS OF: (A) MIXING A FIRST SLURRY OF A RAW DIELECTRIC CERAMIC WITH A THERMOPLASTIC RESIN OF THE ACRYLATE AND METHACRYLATE GROUP, DISSOLVED IN A SUITABLE SOLVENT; (B) CASTING SAID LIQUID SLURRY INTO A SHEET AND PERMITTING SAID SOLVENT TO EVAPORATE, THEREBY FORMING A SHEET OF RAW WARE; (C) MIXING A SECOND SLURRY HAVING SUBSTANTIALLY THE SAME COMPOSITION AS SAID FIRST SLURRY; (D) MIXING INTO SAID SECOND SLURRY A FINELY POWDERED METAL OF HIGH CONDUCTIVITY IN THE RELATIVE PROPORTIONS OF FROM 20% TO 8% BY WEIGHT OF CERAMIC TO FROM 80% TO 92% BY WEIGHT OF POWDERED METAL TO PRODUCE A LIQUID ELECTRODING MIXTURE; (E) APPLYING SAID ELECTRODING MIXTURE TO COAT A SURFACE OF SAID SHEET OF RAW WARE AND PERMITTING THE SOLVENT TO EVAPORATE FROM SAID ELECTRODING MIXTURE; (F) ASSEMBLING A PLURALITY OF COATED SHEETS OF RAW WARE IN A STACK, EACH SHEET PREPARED IN ACCORDANCE WITH STEPS (A) THROUGH (E) ABOVE; (G) APPLYING PRESSURE TO SAID STACK OF COATED SHEETS OF RAW WARE TO COMPACT THE SAID STACK; AND (H) FIRING SAID STACK OF COATED SHEETS OF RAW WARE THROUGH A FIRING AND COOLING CYCLE OF PREDETERMINED TEMPERATURE RELATIVE TO TIME.
